Conservation Windows

Designed for listed buildings and sensitive heritage projects, our Conservation Casement Windows combine traditional aesthetics with discreet modern performance. Slimlite glazing and premium timber make them ideal for properties where authenticity is key.

Overview

Built on the foundation of our flush casement design, this range meets conservation requirements by incorporating 16mm Slimlite krypton-filled double glazing, a subtle yet effective solution for improving thermal efficiency without altering the character of a property.

Made from Accoya timber, known for its exceptional durability and stability, these windows are precision-engineered in the UK and fully customisable using our standard selection of profiles, paint finishes and ironmongery.

 
Key Benefits

  • Slimlite Glazing for Heritage Compliance: Meets conservation guidelines with ultra-slim 16mm, high-performance double glazing that mimics the appearance of single glass.
  • Engineered in Accoya: Offers superior longevity, minimal maintenance and outstanding dimensional stability, even in challenging climates.
  • Refined Operation & Security: Features ball-bearing butt hinges for smooth movement and a multipoint espagnolette lock for enhanced protection.
  • Custom Details: Select from a variety of mouldings, stays, fasteners and finishes to match or complement existing architectural features.
  • Weather-Resistant Construction: Double seals and secure beading provide effective defence against wind and rain, improving interior comfort year-round.

Aesthetic Impact

Every detail of our Conservation Casement Windows is considered with heritage sensitivity in mind, from the flush-fitting sash to the subtle timber profiles and traditional ironmongery. The Slimlite double glazing gives the illusion of single glass with the thermal benefits of double glazing. These windows bring understated elegance to period homes, blending seamlessly into historic façades without drawing attention to modern enhancements.

Whether you're restoring a listed cottage or working within strict planning conditions, this range allows for visual consistency while quietly delivering modern standards of performance.

Tested to PAS24, these windows meet Part Q building regulations for security, ensuring they satisfy both planners and inspectors.
